Description

.Die Erfindung betrifft ein Verfahren zur Aromatisierung von aus einer Zigarette abgesogenem Tabakrauch, ein Zigarettenendstück, insbesondere Zigarettenfilter zur Durchführung dieses Verfahrens, sowie eine Anwendung dieses Verfahrens.The invention relates to a method for aromatizing tobacco smoke extracted from a cigarette, a cigarette end piece, in particular a cigarette filter for carrying out this method, and an application of this method.

Es ist bereits bekannt, zur Erzielung von aromatisierten Zigaretten bei deren Herstellung zum Beispiel den zerkleinerten Tabak, die Zigarettenverpackung oder die Azetatfilter mit einem Aromastoff zu bespritzen. Diese Verfahren weisen jedoch oft den Nachteil auf, dass die Herstellung von aromatisierten Zigaretten infolge der starken Flüchtigkeit des Aromastoffes- einerseits und der starken Affinität des Tabaks gegenüber dem letzteren isoliert von der Herstellung anderer Zigaretten durchgeführt werden muss, da die letzteren sonst ebenfalls einen Beigeschmack erhalten. Wenn die Herstellung von aromatisierten Zigaretten infolge beschränkter Nachfrage nur in relativ kleinen Produktionsmengen erfolgt, dann ist nach jeder Umstellung auf nicht aromatisierte Zigaretten die gesamte Produktionsanlage zu dekontaminieren, was selbstverständlich äusserst umständlich und kostspielig ist, da neben den Reinigungskosten während der gesamten Reinigungszeit die Produktionsanlage stillstehen muss.To achieve flavored cigarettes in their manufacture, it is already known to spray, for example, the shredded tobacco, the cigarette packaging or the acetate filter with a flavoring. However, these processes often have the disadvantage that the production of flavored cigarettes must be carried out in isolation from the production of other cigarettes due to the strong volatility of the flavoring on the one hand and the strong affinity of the tobacco for the latter, since the latter also otherwise have an aftertaste . If, due to limited demand, the production of flavored cigarettes takes place only in relatively small production quantities, the entire production system must be decontaminated after each changeover to non-flavored cigarettes, which is of course extremely cumbersome and expensive, since in addition to the cleaning costs, the production system is at a standstill during the entire cleaning time got to.

Da immer mehr leichtere Zigaretten, das heisst Zigaretten mit niedrigem Nikotin- und Teergehalt beim Rauchen, verlangt wurden, wäre es auch interessant, den mittels solcher Zigaretten erzeugten Rauch zum Beispiel mittels Tabakextrakt oder synthetischem Tabakaroma zu aromatisieren. Die bisher ausprobierten Verfahren weisen jedoch alle den Nachteil auf, dass für eine genügende Aromatisierung relativ viel vom oft sehr teuren Aromastoff benötigt wird, und dass der Aromastoff. nach kurzer Zeit verflüchtigt ist und keine befriedigende Wirkung mehr zeigt, so dass solche Zigaretten nur über eine ungenügende Zeitdauer lagerfähig sind.There are more and more lighter cigarettes, that is cigarettes with low nicotine and tar content when smoking, it would also be interesting to flavor the smoke generated by such cigarettes, for example by means of tobacco extract or synthetic tobacco flavor. However, the methods which have been tried so far all have the disadvantage that a sufficient amount of the often very expensive aroma substance is required for sufficient aromatization, and that the aroma substance. evaporates after a short time and no longer has a satisfactory effect, so that such cigarettes can only be stored for an insufficient period of time.

Aufgabe der vorliegenden Erfindung ist die Schaffung eines Verfahrens, welches die obgenannten Nachteile nicht aufweist, das heisst, welches zum Beispiel die Herstellung von aromatisierten Filterzigaretten ohne eine Kontamination der Produktionsanlage ermöglicht, relativ geringe Mengen an Aromastoffen erfordert, einfach in der Anwendung ist, und eine lange Lagerfahigkeit der derart aromatisierten Zigaretten ermöglicht.The object of the present invention is to provide a method which does not have the disadvantages mentioned above, that is to say which, for example, enables the production of flavored filter cigarettes without contamination of the production plant, requires relatively small amounts of flavorings, is easy to use, and one enables the cigarettes so flavored to be stored for a long time.

Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass man ein mit Aromastoffen beladenes poröses Silikagel im Mundstück der Zigarette verwendet.This object is achieved according to the invention in a method of the type mentioned at the outset by using a porous silica gel loaded with flavorings in the mouthpiece of the cigarette.

Es hat sich gezeigt, dass granulatförmiges, poröses Silikagel ein ausgezeichnetes Adsorptionsvermögen zur Speicherung von Aromastoffen aufweist, und selbst bei offener Lagerung des derart mit Aromastoffen beladenen Aromaträgers bei Raumtemperatur (ca. 18 bis 22°C) über eine Zeitdauer von mehreren Monaten die Verflüchtigung des gespeicherten Aromastoffes so gering ist, dass noch eine genügende Menge an letzterem im Aromaträger gespeichert vorhanden ist. Befindet sich anderseits der derart mit Aromastoffen beladene Aromaträger in einem warmen und feuchten Rauchgasstrom einer Zigarette, dann wird bei jedem Zug des Rauchers an einer solchen Zigarette, wie erwünscht, eine bestimmte Menge an Aromastoff an den vorbeiströmenden warmen und feuchten Rauchgasstrom abgegeben.It has been shown that granular, porous silica gel has an excellent adsorption capacity for storing aroma substances, and even when the aroma carrier loaded with aroma substances in this way is stored open at room temperature (approx. 18 to 22 ° C.) over a period of several months, the volatilization of the stored aroma is so low that there is still a sufficient amount of the latter stored in the aroma carrier. On the other hand, if the aroma carrier loaded with aroma substances in this way is in a warm and moist flue gas flow from a cigarette, then every time the smoker pulls on such a cigarette save, as desired, a certain amount of flavor to the flowing warm and humid flue gas flow.

Es ist vorteilhaft, wenn man als Aromastoff ein synthetisches Tabakaroma, einen natürlichen. oder synthetischen Tabakextrakt, einen natürlichen oder synthetischen Tabakrauchextrakt oder ein Phenoläther, zum Beispiel Anethol oder Anisol, verwendet.It is advantageous to use a synthetic tobacco flavor, a natural one. or synthetic tobacco extract, a natural or synthetic tobacco smoke extract or a phenol ether, for example anethole or anisole.

Es hat sich als zweckmässig erwiesen, wenn man ein Silikagel mit einer spezifischen Oberfläche im Bereich von 300 bis 700m2/g, vorzugsweise von etwa 550 m2/g verwendet. Dabei ist es ferner vorteilhaft, wenn man ein Silikagel mit einem Porenvolumen im Bereich von 0,6 bis O, 85 ml/g, vorzugsweise von etwa 0,73 ml/g, verwendet.It has proved advantageous if one / g, a silica gel having a specific surface area ranging from 300 to 700 m 2, preferably from about 550 m 2 used / g. It is also advantageous if a silica gel with a pore volume in the range from 0.6 to 0.85 ml / g, preferably of about 0.73 ml / g, is used.

Da bei der Verwendung von gewissen Aromastoffen das Adsorptionsvermögen des Silikagel zur Erzielung der gewünschten Abgabe von Aroma an den vorbeiströmenden Rauch zu gross ist, ist es bei Verwendung solcher Aromastoffe zweckmässig, wenn man die Adsorptionsfähigkeit des Silikagel mit Hilfe eines Desaktivierungsmittels auf einen gewünschten Wert einstellt. Dabei kann es vorteilhaft sein, wenn man als.Desaktivierungsmittel Propylenglykol verwendet.Since the use of certain aroma substances means that the adsorption capacity of the silica gel is too great to achieve the desired release of aroma from the smoke flowing past, it is expedient when using such aroma substances to adjust the adsorption capacity of the silica gel to a desired value with the aid of a deactivating agent. It can be advantageous to use propylene glycol as the deactivating agent.

Es hat sich zur Erzielung einer guten Aromatisierung des Zigarettenrauches. ausserdem als zweckmässig erwiesen, wenn man ein mit 16 bis 44 Gew.-%, vorzugsweise mit etwa 30 Gew.-%, bezogen auf das unbeladene Silikagel, mit Aromastoffen oder Aromastoffen und Desaktivierungsmittel beladenes Silikagel verwendet..It has been used to achieve good flavoring of cigarette smoke. Furthermore, it has proven to be useful if a silica gel loaded with 16 to 44% by weight, preferably about 30% by weight, based on the unloaded silica gel, is used with flavorings or flavorings and deactivating agents.

Es ist ferner vorteilhaft, wenn man ein Silikagel verwendet, welches bei einem Aequilibrium von 20°C und 50% relativer Luftfeuchtigkeit bezogen auf die Trockensubstanz des Silikagel, 5 bis 18 Gew.-%, vorzugsweise etwa 8 Gew.-% Wasser enthält.It is also advantageous if a silica gel is used which, at an equilibrium of 20 ° C. and 50% rela tive air humidity based on the dry substance of the silica gel, 5 to 18 wt .-%, preferably about 8 wt .-% water.

Es ist ausserdem zweckmässig, wenn man das mit Aromastoffen beladene Silikagel in mindestens einem Teil eines Zigarettenfilters anordnet.. Dabei ist es vorteilhaft, wenn man das mit Aromastoffen beladene Silikagel mindestens in einen Teil des für ein Zigarettenfilter, zum Beispiel Doppelfilters, bestimmten Filtermaterials einarbeitet.It is also expedient if the silica gel loaded with flavorings is arranged in at least part of a cigarette filter. It is advantageous if the silica gel loaded with flavorings is incorporated into at least part of the filter material intended for a cigarette filter, for example a double filter.

Gegenstand der vorliegenden Erfindung ist ferner ein Zigarettenendstück, insbesondere Zigarettenfilter, zur Durchführung des erfindungsgemässen Verfahrens, welches dadurch gekennzeichnet ist, dass es eine mindestens das mit Aromastoffen beladene, granulatförmige Silikagel enthaltende Kammer aufweist.The present invention further relates to a cigarette end piece, in particular a cigarette filter, for carrying out the method according to the invention, which is characterized in that it has a chamber containing at least the granulate-shaped silica gel loaded with flavorings.

Gegenstand der vorliegenden Erfindung ist ausserdem eine Verwendung des erfindungsgemässen Verfahrens zur Anetholisierung von Tabakrauch.The present invention also relates to a use of the method according to the invention for the anetholization of tobacco smoke.

VergleichsbeispielComparative example

Unter Standardbedingungen, das heisst alle Minuten ein Zug von 35ml Volumen und von 2 Sekunden Dauer, wurden Filterzigaretten der gleichen Marke und mit der gleichen Feuchtigkeit abgeraucht, und parallel dazu von Testpersonen auf den Geschmack überprüft, wobei in den dabei verwendeten Kammerfiltern einerseits mit Anethol beladene, aus Kokosnuss hergestellte Aktivkohle und anderseits erfindungsgemäss mit Anethol beladenes, granulatförmiges, hochporöses Silikagel eingefüllt war.Under standard conditions, that is, a train of 35 ml volume and a duration of 2 seconds every minute, filter cigarettes of the same brand and with the same humidity were smoked, and the taste was checked in parallel by test persons, with the chamber filters used being loaded with anethole , activated carbon made from coconut and, on the other hand, granulated, highly porous silica gel loaded with anethole according to the invention.

Dabei ergaben sich folgende Ergebnisse:

Figure imgb0001
The results were as follows:
Figure imgb0001

Wie man sieht, kann man bei Verwendung von Silikagel als Träger- und Speichermaterial für das Anethol bereits mit einer geringen Beladungsmenge von 10 Gew.-% Anethol (bezogen auf das Gewicht des unbeladenen Silikagels) eine einwandfreie Aromatisierung des Rauches erreichen, wenn die Optimierungsregel beachtet wird, dass Aromastoff und Desaktivierungsmittel zusammen etwa 30 Gew.-%, bezogen auf das unbeladene Silikagel, ausmachen. Da z.B. das Deaktivierungsmittel Propylenglykol bedeutend billiger ist als. Anethol, ist dies auch aus Kostengründen interessant. Bei der Verwendung von Aktivkohle als Träger- und Speichermaterial für das Anethol ist es unmöglich, mit 10 Gew.-% Anethol auf irgend eine Weise eine Aromatisierung des Rauches zu erzielen.As you can see, if silica gel is used as a carrier and storage material for the anethole, even with a small load of 10% by weight of anethole (based on the weight of the unloaded silica gel), the smoke can be properly flavored if the optimization rule is observed will that the flavoring and deactivating agent together make up about 30% by weight based on the unloaded silica gel. Because e.g. the propylene glycol deactivating agent is significantly cheaper than. Anethol, this is also interesting for cost reasons. When using activated carbon as a carrier and storage material for the anethole, it is impossible to flavor the smoke in any way with 10% by weight of anethole.

Zur Ueberprüfung der Lagerungsfahigkeit wurde ferner der unter Standardbedingungen beim Abrauchen von mit einem mit hochporösem, mit 10 Gew.-% Anethol und 20 Gew.-% Propylenglykol Gew.-% (jeweils bezogen auf das Gewicht des unbeladenen Trägermaterials) beladenen granulatförmigen Silikagel enthaltenden Kammerfiltern versehenen Zigaretten bei neun Zügen im Rauch in Partikularphase vorhandene Anetholgehalt bestimmt, und zwar kurz nach. der Beladung des verwendeten Silikagels und nochmals nach etwa drei Monaten, wobei beide Male eine Anetholmenge (in Partikularphase) von 0,44mg/Zigarette festgestellt wurde. Dabei wurde ein unter der Handelsbezeichnung "Polygel W-45" von der Firma Chemische Fabrik Uetikon, U.etikon (Schweiz) hergestelltes Silikagel mit einer spezifischen Oberfläche von 550m2/g Silikagel und einem Porenvolumen von O,73ml/g Silikagel verwendet.To check the storage ability, the under standard conditions when smoking cigarettes provided with highly porous chamber filters containing 10% by weight of anethole and 20% by weight of propylene glycol (in each case based on the weight of the unloaded carrier material) containing chamber filters containing nine puffs in the smoke Anethole content present in the particulate phase is determined, shortly after. the loading of the silica gel used and again after about three months, both times an amount of anethole (in particulate phase) of 0.44 mg / cigarette was found. A silica gel produced under the trade name "Polygel W-45" by the company Chemische Fabrik Uetikon, U.etikon (Switzerland) with a specific surface area of 550 m 2 / g silica gel and a pore volume of 0.73 ml / g silica gel was used.

Anstatt das mit einem Aromastoff beladene Silikagel in die Kammer eines Kammerfilters einzufüllen, ist es auch möglich, dieses in einem in axialer Richtung mittels zweier Abschlusswandungen, deren Filterwirkung vernachlässigbar ist, verschlossenen Mund- oder Endteil vorzusehen, so dass zum Beispiel der Teer- und Nikotingehalt des durchströmenden Rauches praktisch nicht verändert wird und somit dem Rauch einer filterlosen- Zigarette entspricht, anderseits der durchströmende Rauch jedoch zusätzlich aromatisiert wird.Instead of filling the silica gel loaded with a flavoring substance into the chamber of a chamber filter, it is also possible to provide it in a mouth or end part which is closed in the axial direction by means of two end walls, the filter effect of which is negligible, so that, for example, the tar and nicotine content the flowing smoke is practically not changed and thus corresponds to the smoke of a filterless cigarette, but on the other hand the flowing smoke is additionally flavored.

Es ist auch möglich, das mit einem Aromastoff beladene Silikagel bei der Herstellung eines Zigarettenfilters mittels einem Haftmittel zwischen den Fasern des Filtermaterialstranges anzuordnen. Bei einem Doppelfilter würde man das mit Aromastoffen beladene Trägermaterial vorzugsweise in dem Tabakteil der Filterzigarette benachbarten Stöpsel des Filters anordnen.It is also possible to arrange the silica gel loaded with an aroma substance in the manufacture of a cigarette filter by means of an adhesive between the fibers of the filter material strand. In the case of a double filter, the carrier material loaded with flavorings would preferably be arranged in the tobacco part of the filter cigarette adjacent to the plug of the filter.
